... do so dozens of times in our labs and we see airborne contaminants very, very rarely - the contamination is almost always from poorly sterilized loops or from their own butter-fingers!). That being said, the lids are best kept open as little as possible still - after all there is always a chance ...

... the lids are closed and the plates are packed into a plastic bag they also stay sterile for several weeks in the refrigerator.
